Big Loads - Post Photos Number 2

11r22.5 rubber

 

Does Detroit not offer a 600/2050 or did you not need it with the super low reduction?

 

Nice truck how long did you have to wait for them to get it built?

 

The engineers would not approve it with the aux. there a 3 spd rated for it but it runs about $25k and was outside my budget

 

Same boat I wound up in. Allison engineers wouldn't approve it for me either. Most shops are surprised they approved the 600/1850 with the 4700RDS.

 

Seemed like Ever...

I started the first draft in Aug I think, and after the back and forth with engineering ordered it at the end of Oct. Western Star fiddled around with it and I picked up at the factory today and dropped it at the dealer for them to do the pre-delivery stuff

 

I tried very hard to get a viable Allison solution but could not get an approved solution. I Gave them 212k envelope with a 15% start ability requirement. The solution they came back with was a 6.13 rear end ratio with a 4 spd aux and a 560/1850 limit. They were still hedging even at deep a ratio. It was going to be a road speed Nightmare - so I ended up not going with that path

 

I wasn't fully involved in the ordering process but the build sheet lists 190K at 6%. Not very often I run west so hitting grades like that with the 11 fully loaded may never happen. If they do I will likely be locked to 1st and just taking it easy.

The T880 also only has a max of 1330 SQ IN radiator. It's the biggest they offer. Would have had to get a wide nose T800 to get the 1780 radiator. Could get interesting if i have to pull heavy in the south west during the summer. Going to have to really keep an eye on the temps then.

 

Just have your company call
me I will Do All the southwest they need.

You go to West Virginia ....
